Photocatalytic potential of bio-engineered copper nanoparticles synthesized from Ficus carica extract for the degradation of toxic organic dye from waste water: Growth mechanism and study of parameter affecting the degradation performance

摘要

A facile and useful approach to the removal of possible health and environmental hazardous organic dye Alizarin Yellow R was completed by utilizing copper nanoparticles synthesized from Ficus Carica fruit extract. The polyphenols, proteins, and biomolecules present in the fruit extract were involved in the bio-reduction of Copper nanoparticles. The photocatalytic activity of the Copper nanoparticles was examined by the degradation of toxic organic dyes such as Alizarin Yellow R. These results displayed that photocatalytic capacity of Copper nanoparticles towards Alizarin Yellow R dye was more significant and maximum degradation performance of Alizarin Yellow R was 89.71%, respectively. Different parameters that affect the degradation performance were also studied to determine the ideal conditions for maximum photocatalytic efficiency. The chemical kinetics and possible photocatalytic degradation mechanism were also described. Due to the high degradation performance and stability, it could be possible that copper nanoparticles may have some beneficial effects in organic dyes removing from different industries wastewater in the future.
